438/16 nm VersaChrome® tunable bandpass filter
VersaChrome filters do what no thin-film filter has done before – offer tunability over a very wide range of wavelengths by adjusting the
angle of incidence with essentially no change in spectral performance. They combine the spectral characteristics and two-dimensional
imaging performance of a thin-film filter with the wavelength-tuning flexibility of a diffraction grating.
